Meta-analysis: Forest Plots with lines of overall effect and no effect

[Althia Francis]

I used the "meta set" option to conduct a meta-analysis. I want to include lines of overall effect and no effect in the forest plot. I tried using the "meta forestplot, esrefline nullrefline" option but it says option not allowed. Any suggestions on how I can add lines of overall effect and no effect in my forest plot.

We would need more details about your data and commands used prior to meta foresplot. The following example works fine.

 
use https://www.stata-press.com/data/r16/bcgset, clear
meta forestplot, esrefline nullrefline
